Definition of Unearned Revenue in Accounting. Unearned revenue is the same thing as deferred revenue. In accounting, unearned revenue is a liability. It is a liability because even though a company has received payment from the customer, the money is potentially refundable and thus not yet recognized as revenue.
Unearned revenue (deferred revenue) refers to funds received by a seller for goods or services not yet delivered to the buyer. This article further defines and explains unearned revenue and deferred revenue, with numerical examples. The unearned revenue situation is familiar in many kinds of businesses.
